OIROULATING HEATING STOVE.

Application filed March 23, 1928.

The invention relates generally to circulating heating stoves and moreparticularly to stoves ofthis type in which the heating unit is enclosedin a concealing cabinet preferably adapted and constructed to present afinished and ornamental appearance.

One object of the invention is to provide a new and improved cabinet forenclosing a heating unit which embodies a closure means therefor'of asimple and practical character movable to an out of the way position topermit access to the interior of the cabinet for operating purposes. 7

Other objects and advantages will become apparent in the followingdescription and from the accompanying drawings 1n which:

Figure 1 is an elevational view of the invention, parts thereof beingbroken away to disclose the operation of the closure means. r

Fig. 2 is a fragmentary view in perspective taken from the interior ofthe cabinet looking outwardly.

Fig. 8 is a fragmentary view in elevation,

looking laterally from the interior of the cabinet, of one of theclosure sections in open position.

Figs. 4 and 5 are enlarged fragmentary detail views in section and planrespectively showing the upper guide bar and follower.

Figs. 6 and 7 are enlarged fragmentary side and face views respectivelyshowing the construction of thelower guide rails and rollers.

WVhile the invention is susceptible of various modifications andalternative constructions, I have shown in the drawings and will hereindescribe in detail the preferred embodiment, but it is to be understoodthat I do not thereby intend to limit the invention to the specific formdisclosed, but intend to cover all modifications and alternativeconstructions falling within the spirit and scope of the invention asexpressed in the appended claims.

In the drawings a cabinet, constructed in accordance with the objects ofthis invention, is shown as comprising generally an upright outer caseor cabinet having a top 10, bottom 11, and a front, back and sides. Ifdesired suitable legs 15 may be employed to space the cabinet from thefloor. The cabinet is of a size to enclose a suitable heating unit orstove, generally designated as 16, which may be of any preferred con-Serial No. 264,154.

struction and design. The cabinet may be as ornamental in appearance asis desired and preferably the ornamentation is of such character thatdesigns in grille work 17 or the like may be employed. Thus a freecirculation through the cabinet, of air to be heated by the stovemounted therein, is insured without detracting from the appearance ofthe cabinet.

As shown the stove is mounted in the cabinet with the fuel and ash pitdoors 18, 19, which are customarily provided in such stoves, facingtoward the front of the cabi net. In order that access to the doors 18,19 may be had, the front of the stove has an opening, the margins of theopening being defined by a frame 20 which may be formed as an integralpart of the front or may be rigidly affixed thereto. Preferably theupper edge of the frame is turned inwardly to provide a short flange 21(Fig. 4) the purpose of which will become hereinafter apparent.

In the present embodiment the preferred form of closure means (Figs. 1and 2) comprises a pair of flat substantially rectangular doors 22 whichare adapted normally to extend across and completely close the frontopening of the cabinet. A simple form of means for insuring that thedoors assume the proper position in the frame and for providing rigiditybetween the doors comprises an offset lug 22= projecting laterally froma position near the top and bottom of the inner edge of one of thedoors, which lug is adapted to engage a complementary boss 22 formed inproper position upon the other door. Any suitable form of operatinghandles 23 may be secured in the customary manner upon the doors 22.

The means by which guided movement of the doors is attained comprises,in the present instance, a pair of guide wheels, generally designated as24, mounted near the lower edge of each of the doors, which wheelsengage suitable guide rails 30, 31 shaped properly to direct and guidethe movement of each door. Means also is provided on each door tosupport the upper portions thereof during the opening and closingmovements.

The guide wheels 24 may be of any suitable form, and in the presentinstance comprise grooved rollers 25 (Figs. 6 and 7) each of which ispivotally mounted on an L- the cabinet is simple.

shaped bracket 26 which carries a vertically extending rod 27. The rod27 is journaled in both legs of a U-shaped bracket 28, which in turn isrigidly fixed to a pair of lugs 29 suitably mounted upon the door. Thus,each of the rollers 25' is spaced inwardly of the cabinet from thedoors, and are mounted in such manner that relative pivotal movement ispermitted.

The guide rails 30, 31 are in the form of tracks provided for each doorand are mounted upon the bottom of the cabinet in a position to beengaged by the grooved rollers 25. As may be seen in Fig. 2, four guiderails are shown, there being a set of two rails for each of the doors.The inner rails 30 of the sets are appropriately formed and positionedrelative to the doors so that as the inner rollers follow the rails theinner side of the doors will move in a substantially straight linelaterally of the cabinet. The outer rails 31 are curved so that as theouter rollers follow the rails the outer side of the doors move firstdiagonally inwardly a short distance and then swing rearwardly to occupya position near the rear corners of the cabinet.

TMeans is provided for guiding and supporting the upper portion of thedoors during the movement thereof. This means, in

the present instance, comprises a guide bar 32 (Fig. 4) secured to aplurality of lugs 33 which space the bar rearwardly from the front ofthe cabinet with the bar extending laterally across the cabinetsubstantially in registry with the margin of the upper edge of the frame20. Each of the doors carries an upwardly extending follower hereinshown in the form of a finger 34, which is rigidly secured to lugs 35preferably positioned near the inner upper corners of the doors. Thefingers 34: on the doors are adapted to be inserted between the inwardlyextending flange 21 on the upper side of the frame 20 and the guide bar32 for guided sliding movement therebetween.

'The operation of the closure means for Assuming that the doors are inclosed position and that it is desired to open them, it is onlynecessary to grasp the operating handles 23 and toexert a force actingto separate the handles.

Such a force will cause the outer edges of the doors to move diagonallyinwardly a short distance, and then as the outer rollers follow theguide tracks 31, these edges of the doors will be swung sharply inwardlyof the cabinet. At the same time the inner edges of the doors have beenguided by the inner rollers upon the inner guide rails 30 to a posltionadjacent the front side of the cabinet. Thus in the open position of thedoors only the inner edges thereof may be seen. By'this construction itwill be apparent that a closure means for the front opening way positionat the sides of the cabinet when it is necessary, for any reason, toobtain ac cess to the heating element positioned in the cabinet.
